Well, no one wants to look at the Taiko diffs, so I'll pop in real quick.
[General]
Please set Preview Time to 01:44:062 on the Taiko difficulties.Center the difficulty settings. (AR/CS to 5).
Change the Sound Samples to Normal on all Timing/Inherits. Using Soft makes it a little too quiet.
[Oni]
00:23:062 (141) - Use a d here, it fits the lower pitch of the vocal a bit better.
01:34:162 (606) - Try using a d here and add a d on 01:34:087. This can allow for a little overmap and fit the pause of the vocal a bit more on 01:34:162.
02:03:562 - 02:07:162 - This seems a bit lazy. Maybe clean it up a bit more, here's a suggestion, with the first note being a D:
02:10:762 - 02:14:362 - Same as above.
02:21:262 (43,44,45,46) - This part is 1/3, so it would be dddk.
03:32:883 (528,529) - Switch these around to kd, it fits a bit better with the chimes.
03:37:465 - Change this timing section to 5% volume so the spinner is quiet, sounds a lot better.
[Muzukashii]
00:02:362 (8,9) - Make this into a d d k ending on 00:02:662 to match 00:04:762 (18,19,20,21,22).
00:14:662 (67) - 00:15:262 (71) - Change these both to d. This would be easier to play and you would be able to add a note that's missing on 00:15:412 - which could fit either d or k.
00:20:812 (94,95) - Switch these around to k d. This fits the vocals more and it goes with the next rhythm.
02:21:412 (8) - Move this to 02:21:262, this fits a little better since the 1/3 kind of makes this feels off on a 1/2.
02:50:212 (1) - Try making this a slider, it helps you build more into the kiai by giving you more to add at 02:51:562.
03:10:762 (1) - Move this back 1/4 or 1/2 so you can add a note at 03:11:662. This would show the vocal a little more. When people play spinners, it usually ends before the end of the spinner.
03:37:465 - Change this timing section to 5% as said before on the Oni. Quiet spinners at the end of a map where there's nothing is just tasty.
Both are pretty fun, I really hope this helps get progress towards ranking.
